Title: Method for measuring the speed of biaxial, all-wheel-drive tractors, in particular for agriculture
Inventor: SCHIMMEL JOHANNES DIPL ING
IPC: G01P3/56
Filed: 1983-07-01
Abstract: In a method for measuring the speed of biaxial, all-wheel-drive tractors, in particular for agriculture, having disconnectable front- wheel drive, it is proposed that during the traction work with all-wheel drive, the front-wheel drive is briefly interrupted and in this case the tractive force of the tractor is measured in common with the speeds of its front and rear wheels. The driving force coefficient/slip characteristic corresponding to the respective ground conditions is established from the measured values determined or is selected from a prescribed family of curves, and the slip assigned to the driving force coefficient in the case of all-wheel drive is determined with the aid of this characteristic. This renders it possible for the speed of biaxial, all-wheel-drive tractors to be measured in a simple way and with relatively simple means. <IMAGE>

Title: Device for discharging articles packed in cardboard boxes in commissioning systems
IPC: B65G1/08
Filed: 1983-09-10
Abstract: Discharging devices in commissioning systems for discharging articles packed in cardboard boxes each have their own drive systems, which is expensive and, because of the number of drives involved, prone to failure. The new commissioning system provides for combination of a multiplicity of discharging devices with their article supply chutes into a single unit and an arrangement, so that they are freely mounted in a horizontal direction, of all the pushing devices which eject the articles from the supply chutes on a slide which is operated by means of a crank mechanism. An electromagnet is also arranged on the slide under each pushing device, near its free end, the said electromagnet being excited by means of a computer-controlled pulse generator and causing the pushing device or devices to adopt their operating or ejecting positions. Cycle times of less than 1.5 seconds can be achieved by means of this very simple and robust device.
Patent DE-3333717-A1 (DE)
Title: Device for removing dirt or air particles from an ink jet print head of a printing mechanism
Inventor: ZEISING NORBERT DIPL PHYS
IPC: B41J2/165
Filed: 1983-09-17
Abstract: In ink jet printing mechanisms having the smallest outlet nozzles required for producing very small ink droplets, there is the risk of foreign bodies blocking these jets. Such blocking can also easily occur due to ink having dried in the nozzles or as a result of ink decayed by ageing. Furthermore, in ink jet print heads, entry of air bubbles must be avoided since these prevent ejection of ink droplets from the outlet nozzles. The risk of outlet nozzles becoming blocked is even greater in ink jet print heads having several ink chambers containing inks of different colours. The invention is based on the object of providing a device for removing dirt or air particles from ink jet print heads producing multi-colour records, which device has a simple construction and is suitable for cheap mass products. This object is achieved in that the supply hoses 17, 18, 19, which connect the ink jet print heads in terms of flow to ink reservoirs 14, 15, 16, rest in each case with a portion 25, 26, 27, 28 against an inner wall 29 of a pump housing 30, arranged spirally one above the other. These portions 25, 26, 27, 28 are charged by a squeezing device progressing spirally in the longitudinal direction and at intervals successively and separately. The drive for the squeezing device can be of low-capacity and inexpensive construction. <IMAGE>

Patent DE-3344872-A1 (DE)
Title: Voltage divider
Inventor: THIEL EGON DR
IPC: G01R1/20
Filed: 1983-12-12
Abstract: A voltage divider is already known which consists of a first resistor having a resistance value R1 and of a second resistor having a resistance value R2, the second resistor being connected in series with the first resistor. Particularly in the case of extremely high voltage divider ratios, the division ratio of such a voltage divider is dependent on the magnitude of the input voltage and on the temperature, when implemented using thick-film technology. According to the present invention, this undesirable dependency is avoided in that a series circuit consisting of a third resistor having the resistance value R11 and of a fourth resistor having the resistance value R12 is connected in parallel with the first resistor, and in that the cross-section of the second resistor is larger than that of the first resistor. <IMAGE>

Title: Epicyclic gearbox with a forward gear designed as an overdrive gear
Inventor: FOERSTER HANS-JOACHIM PROF DR
IPC: F16H63/30
Filed: 1984-02-28
Abstract: For the purpose of connecting an input shaft to an output shaft, an epicyclic gearbox has an epicyclic coupled gear unit comprising two single-web epicyclic gear sets connected to one another by two coupling shafts. To form a forward gear designed as an overdrive gear, one of the coupling shafts is, in addition, connected to the output gear member of an epicyclic overdrive gear mechanism, which can be driven at least indirectly by the input shaft via its input gear member. To form the transmission ratios in the coupled gear unit, use is made of two gear-change brakes, respectively connected to one coupling shaft and to one uncoupled gear member, and of in each case one forward-gear clutch and reverse-gear clutch which can be connected into the torque transmission path. In order, together with the overdrive gear, to obtain more than four forward gears, a new manner of association both of the output shaft - via the forward-gear and reverse-gear clutch - and of the gear-change brakes with the gear members of the coupled gear unit ensures that the transmission ratio of the overdrive gear mechanism can be superimposed multiplicatorely on one or more transmission ratios of the coupled gear unit and that the speed ratio of the overdrive gear can only be formed in the overdrive gear mechanism.

Title: Method for the production of cores for metal casting
Inventor: SAKAMOTO TOSHIO
IPC: B22C9/10
Filed: 1984-07-31
Abstract: To produce split sand cores, refractory particles, such as quartz sand, are mixed with two binders, one of which consists of an inorganic substance, such as a silicate, and the other consists of a starch, and preferably with water. The two binders serve to overcome the disadvantages of the binders when used individually. The mixture is then introduced into a core box which is formed essentially of materials which are permeable to microwave energy. When microwave energy is made to act through the core box, the mixture cures in the shape of the core box cavity. To produce moulds with a higher surface stability at room temperature, the starch and the water are first of all mixed to give a paste, whereupon this paste is added together with the inorganic binder to the refractory particles, a uniform dispersion of the starch in the mixture thereby being ensured.

Title: Intercommunicating gangway element with foldable intercommunicating gangway
Inventor: SOLITC JOSIP
IPC: B61D17/22
Filed: 1984-12-28
Abstract: The intercommunicating gangway element with foldable intercommunicating gangway (4) and sealing devices, in particular for person-intercommunicating gangways (21) has means (13) for protecting persons from external influences, in particular pressure waves. The combination of the intercommunicating gangway with an angular frame (1), which is connected to the end (20) of the wagon body by means of resilient elements (3) and a sealing diaphragm (2) in a floating or cardanic fashion, also serves this purpose. An intercommunicating component (9) which can be walked on is connected via a swivel element (18) to the fixed component (16) of a telescopic intercommunicating arm (15). This intercommunicating component (9) is mounted together with the components (15, 16), as one unit or independently of one another, on the angular frame (1) so as to be swivellable in the vertical direction. The telescopic intercommunicating arms (15) can be extended and coupled by means of one coupling (24) in each case. This further development and simplification on the basis of the aforesaid intercommunicating gangway element, in particular using the angular frame known from the said gangway element, permits the intercommunicating gangway element to be constructed as an integral component of the angular frame so as to be sealed against external weather influences and pressure waves. <IMAGE>
